The CMONE SF125 125A Manual Changeover Switch is a heavy-duty power transfer device designed for switching between two power sources such as the grid and a generator or inverter system. With a higher current capacity and 4-pole design, it is ideal for larger homes, commercial spaces, and industrial setups that require stable and safe power switching.
